BARREL-HEADING MACHINE.

, Application filed August 3, 1927. Serial No. 210,355.

This invention relates to barrel heading machines of the type employingsuction mea-ns for handling the heads.

rlhe main objects of this invention are kto provide improved means formaintaining the suction head of the machine in a substantially horizontal plane during its movement in picking up the barrel head and placingit in the end of the barrel being headed; to provide im noved means Vforcompressing the barrel staves during and subsequent to the headingoperation; and to provide improved leverage means for forcing the barrelhead into the barrel. f

An illustrative embodiment of the invention is shown in the accompanyingdrawings wherein Y Fig. 1 is a side elevation of the machine with thebarrel ,being worked upon, and suction head when inserting a headtherein, shown in dotted outline.

Fig. 2 is a front elevation of the machine.

Fig.` 3 is a top plan view of the same.

Fig. l is a sectional View taken on line l-l of Fig. 1.

Fi 5 is a sectional detail taken on the line 5 5 of Fig. '1.

In the present barrel heading machine which is the subg'ect matter ofthis application, the suction head is mounted sov as to be in ahorizontal plane at all times. At the same time, it is shiftablevertically and swingable sidewise, the head maintaining its horizontalposition, however, throughout such movement.

rlhe advantage of this construction is that the chime in the upstandingends of the barrel staves forms an annular horizontally disposed groovefor receiving the beveled edge of the barrel head, and when the suctionhead which carries Vthe barrel head is lowered into the upper end of theharrel being worked on, the barrel head will automatically be in correctangular position to fit into the chime without necessitating rocking orshifting of the suction head to bring it to a horizontal pla-ne. liliththisl construction, considerable time is saved and, of course, thatmeans a reduction in manufacturing cost.

ln the construction shown in the drawings, a suitable framework 1,rpreferably formed of angle irons. supports a vertically Vdisposedcylinder 2 which communicates at its upper and lower ends with suctionpipes 3. and f1 respectively, which join a main suction pipe 5.

A sleeve 6 surrounds the cylinder 2 in spaced-relation thereto and isvertically slidable thereon. The medial portion of the cylinder 2 isprovided with an aperture 10 vthrough the wall thereof for providingcom- -ed shank 1G which embraces opposite sides of the duct 12 ispivoted thereto at 17 adjacent the lower end thereof. A prize bar 1S isslidably mounted between the side arms of an inverted U-shaped bracket19 near one end thereof and the other end thereof is bifurcated tolikewise embrace the duct 12, the bifurcated arms thereof beingp`votally attached to the bifurcated arms 16 of the handle at the point20. A coil tension spring 21 which has one end thereof attached to thebar 18 and the other end thereof to a clip 19 fastened to the head 14,is provided for normally holding the bar 18 in the position shown in 1of the drawings. An inverted V- shaped bracket 22 is rigidly mounted onthe framework 1 for receiving the outer tip end of the bar 18 when thebar is shifted endwise by movement of the handle 15 about its pivot 1Tto a horizontal position. In this manner the bar 1S and the bracket 22serve to bring the suction head and the barrel top held thereon intoregistration with the open end of the barrel. lllhen the handle 15 isrotated to the position shown in dotted lines in Fig, 1, the bar 18 ismoved relative to the bracket 19 and into the guide bracket 22, and thehandle is restrained from further rotation by the engagement of theright hand end portion of the bar 18 with the pivot pin 17 of thebifurcated shank 16. Vhen further pressure is applied on the handle, thesuction head 14 together with the ducts 11 and 12 are moved downwardlyfor engaging the barrel head on the end of the barrel.

Means are provided for aiding and assistthe unit which comprises'thesleeve 6, duct 11, duct 12 andsuction head 14 carried thereybyaudcomprise a pair of ropes or cables and each et whichV has one endattached to eye-bolts 27 and 2,8 respectively, which in v turnaresecured to a plate 29 which forms the lower closure ot the sleeve r6.lThe opposite ends oi the cables 25 and 26 pass upvardly and over pulleywheelsV 33 and 34 respectively' and then downwardly within verticalktubes 35 and 3.6 respectively, the lower ends of each being attached tocounter- ,v'eights13?n which are slidably housed within the tubes and36. A similar plate 30 forms closure for the upperend of the sleeve 6and both closures are provided with openings therethrough for receivingthe vertical-ly disposed rods' 31 and 32 which provide guideways'i-orthe' unit.

lvleans are provided for drawing together the upstanding ends ont thestaves of the barrel being headed'and comprise` a iieXible cable '40having its ends anchored at 41 .to the yiirznnework and thev medialvportion thereoi formed in a loopwhich is adapted to be placed aroundthe upper ends ofthe barrel staves.

Thetwo sides of the looped cable 40 pass' through the medial portion ofa member 42 which carries a pair of pulley Wheels 43 and 44 pivotallymount The member 42 is horizontally slidable on the framework V1 towardand taway from the barrel 'being worked upon and movement thereofiscontrolled by a toot lever 46 pivoted at oneend 47 yto the supportingframe 1 and provided with a coil tension spring 48 which bears betweenthe trameand the lever for normally holding it in a substantiallyhorizontal position. Lever 46 has a vertically disposed link 49pivotally attached thereto, vthe upper end of which is pivotallyconnested 'at 50 to one end of each of links 51 and 52.V The oppositeend of 4link 51 is pivoted at v53 to the 'framework 1 and these links,when in operative position are in the form oi an inverted V as shown inFig. 1 of the drawings. Link 52 has its other end connected to themember 42 so as to shift the same horizontally toward the barrel beingworked upon when the i'oot lever 46 is depressed. The outer or bearing:tace or' lmember 42 is arcuate so as toiconiiorm to the outer peripheryof a `barrel being headed as shown particularly in Figs. 3 and 4 of thedrawingsl The frameworkl is formed so as to provide'a table 60 'forsupporting a pile of barrel heads 61 preparatory to their being placedin the barrels being headed. An upstanding semi-'circular guideretaining member 63 is provided on lthe tab-le 6,0 for keeping thesupply of Vbarrel headsv in'position thereon; l In the operation of thismachine, a stack of barrel heads is piled on the table 6() and edthereon for bearing against the cable 40.

the suction fan (not shown) which is connected to the duct 5, isstarted. Thiscauses they air to be drawn in through thefsuct-ion head 14which, with ducts 12, 11 and sleeve 6 operate asa unit. A Vbarrel isplaced in position and the cable 40 placed therearound, and partiallydrawn tight by depressing the foot lever. `The' suction headunit is thenswuno' over to the supply of barrel heads and lowered down against thetop head. The suction lifts this barrel head fromA trie pile whenthehead is raised and it is then swung vabout a vertical lairis until it isdirectly above the barrel being headed, at which time the handle 15 ispulled downwardly-into a sul stantially horizontal position; Thismovenient of the vhandle 15 causes the prize bar 18 to move endwise soas to pass betweenV the upstanding sides of the inverted, Yfl-shapedbracket 22. Further downward movement ot the handle 15 causes the 'bar18 to bear against the top end oi the bracket22 and thus center thesuction head over the barrel as it moves downwardly to bring the barrelhead which is being carried thereby into the chime of the barrel beingheaded.' The foot lever 46 is then further depressed, thus securelyclamping the head in the barrel. The suction head is next liftedupwardly, thus breaking the suction and' releasing the barrel head.

.A suit-able hoop is then placed around the top of thebarrel andthe footlever 46 .re-

leased, thus taking the tension oli o .the cable 40, thereby releasingthe barrel. Raising and lowering out the suctionhead unit is renderedcomparatively easy by reason ofthe counterweights 37 which are soproportioned .as to permit ready raising and lowering of the suctionhead unit. l l

Although but onespecic embodiment of vthis invent-ion has been hereinshown and described, it is to be understood that numerous details of theconstruction shown may be altered or omitted without departing from thespirit` of this invention as defined .by the following claims. i
